My invention relates to a supporting structure for large plate glass panes and has particular reference to what is termed the sash portion of sucha structure, this portion forming the supporting base of positioning the window panes of large display windows.

An object of my invention is to facilitate the installation of large plate glass panes in store fronts, and the like, at the same time providing a structural element which is artistic and which may be made in conformity with any desired type of architecture.

A more specific object is to eliminate all surplus elements which customarily form portions of the built up composite metal Window sash for such glass plates and to provide a construction which embodies a minimum number of cooperating elements which may be quickly positioned with respect to one another and readily secured in position to properly support a plate glass in a manner superior to what has heretofore been available.

In suggesting a specific use for my improved structure, I contemplate primarily its usein conjunction with store fronts andan important object resides in'rendering the structural elements architecturally beautiful, simple and practical to install. and as inexpensive to manufacture as possible.

Various other objects and meritorious features of my invention will be apparent from the following description taken in conjunction with the drawing, wherein like numerals refer to like parts throughout the several figures and wherein:

Fig. 1 illustrates inrperspective what I shall hereafter term the face plate ofmy composite structure.

Fig. 2 illustrates in perspective what I shall term the set plate thereof,

Fig. 3 is a section of my improved structure after assembling and, 1

Fig. 4 illustrates a modification of the assembly shown in Fig. 3. Referring to the drawing the face plate, which I have broadly designated by the nu meral 10, includes a'channel shaped bottom portion 12, the lower wall 14 of which channel is adapted to seat upon a. supporting frame 16 such as the sill or jamb. The face plate.

' sitioned. Supporting blocks 43 are inserted of the plate may be designedwith desired configuration, and rolled to provide any desired ornamental features such as the steppedin portion 16. The upper portion of the-face plate consists also ofa channel shaped por tion 20, the inner wall 22 of which "constitutes a positioning surface for' the glasspane which is to be utilized. 1 7 Depending from the wall 22" along the M length thereof is a third channel shaped por 6 tion 24, somewhat offset from the perpendicular and extending forwardly toward the front of the face plate as clearly illustrated. The inner wall 26 of this depending channel shaped portion, and the bottom wall 14 of 6 channel portion 12 are designed to co-operate, in a manner to be described, with the set The bottom of channel shaped portion 24 (M is cut away as at 28 at spaced apart intervals T along the length of the unit and elongated slots 30 are provided between "the cut away portions. h 1 i i 1,

The set plate which I shall broadly- ,designate by the numeral 32 comprises abottom 5 set'portion '34 which is adapted to rest upon the supporting surface 16, and includes a raised lip portion 36 which is adapted to seat upon the bottom wall 14 0f faceplate channel 12. The bottom portion 34, on assembling the 1) structure, may be secured to the support surface 16 by any desired means, such as the wood screw 38. The rear wall 40 of set plate 32 preferably extends vertically, altho this is not essential, and is provided along its up,- 5 permost extremity with a turned over portion 42 which is adapted to firmly position the rear Wall26 ofthe channel shaped portion 24 of the face plate.

It will be understood that in the structure illustrated in Figs. 1, 2 and 3, the set plate will first be positioned upon the supporting surface 16 and the face plate subsequently poin the openings 28 and along the top of these is seated a strip 44 of some material particularly adaptableto constitute a seat for edge of a glass plate. While no particular material need be specified herein, lead is quite frequently used for this-purpose. 1'00 i The set plate 32 includes the gutter like portion 48 and the rear positioning surface 50, which later cooperates with face 22 of the face frame 10 to position the glass plate 46. The glass pane is positioned upon the supporting blocks 43 after the set plate is in stalled and thereafter the face plate is disposed in place.

At spaced apart intervals along the bottom of gutter like portion 48 there are apertures 52which are so spaced that they are each adapted to cooperate with slots 30. To secure the assembly in position it is only necessary to insert screw 54 in apertures 52 and, by virtue of the elongated slots 30, the extremities of these screws 54 will always find an opening in the face plate 10 whereby the two plates maybe secured together. Obviously this constitutes a substantial improvement over such structures as providea plurality of apertures such as 52 in each of the plates, wherein the apertures must be accurately aligned before the screw 54 may be tightened.

By virtue of the angular position of securing screws 54 it will be apparent that the tightening up operation will draw the face portions 22 and 50 of the two plates respectively firmly against the sides of the glass pane 46.

The gutter 48 functions as an effective drain for any moisture which may accumulate at the base of the window pane. Drainage holes 49 are provided in the gutter 48 and weep holes 15 are provided in the base channel of the face plate. These holes also afford ventilation for the usual purposes. The use of elongated slots 30 materially decreases the time necessary for assembling the structure inasmuch as there is no necessity for feeling about to accurately align two thread apertures, and it will be apparent from Fig. 3 that the set plate bears firmly upon the face plate along its bottom and top extremities, which also constitute the front and rear extremities.

In the setting up of my assembly the edge of the flange 26 seats between the wall 40 and overhang 42 of the set plate so that the tightening of the screws exerts a tension through the channel. 24 to urge the face 22 of the face plate toward the flange 50 of the set plate,

A distinct advantage of my structure resides in the fact that the complete assembling operation may be performedfrom within and that the fastening means do not extend through the front face of the structure. The tlghtening screws 54 are inserted and tightened from the rear after the assembly is in position.

A somewhat modified structure is illustrated in Fig. 4 wherein the bottoms 56 of the face plate is provided with a raised lip 58 at its rear extremity, this lip being adaptedto bear downupon the bottom supporting surface 60 of the set plate. In this instance the face plate will first be secured in position and the set plate subsequently positioned. The glass pane 46 is inserted as hitherto described and the screws 62 utilized in the same manner as hitherto described to tighten the assembly in position.

Having illustrated, with modifications, my improved structure, various other modifications will be apparent to those skilled in the art and for that reason I intend to limit myself only within the scope of the appended claims.
